    Dynaco Mark III build

    Post by JunkyJan on Wed Oct 20, 2010 3:20 pm

    Hi Gentlemen

    At the risk of boring the heck out of you all, here is a series of photos I took during my Mark III assembly:

    Power & O/P trannies mounted - I wanted a "classic Mark III" look so I sprayed the transormer bells the closest to the old Dynaco gray I could find (heat resistant paint, baked it according to instructions @ 300 deg. F for 3 hours!). The color balance (tungsten lighting) is pretty bad in this pic, the final pictures give a better idea of what it really looks like...



    VTA Mark III board constructed, wanted to put all caps under the board but turns out the tall caps could nout fit in the avaialble space - had to move it to the top:



    Underside of VTA boards, I went with Auricaps - NOTE: I decided to put Auricaps in the input path as well - not included in the kit - Auricaps on the two boards totalled around $100! (cheap compared to some exotic cap brands that will cost you $250 for ONE cap).



    Initial wiring, I used gold-plated 3-way sockets for the speakers + gold-plated input jack:



    Wiring mostly completed, has been "neatened up" considerably since this pic was taken. The location for the triode mode switch is REALLY BAD - but I didn't want to drill holes into the chassis:



    Up and running! The color in this photograph is better balanced, that is the actual tranny bell color:



    Making sweet music! There are a few things that bug me about the Mark III chassis layout, I wish the speaker & power connections were on the back. Ah well, a small price to pay...



    ....Anyway, thanks for looking & sharing my fun, folks!!
    Sincerely

    Exactly which paint was that for the transformer covers? Can you quote a brand and part number?

    Thanks.

    While waiting on Jan to give the definitive answer, I will comment that having served in the US Navy for five years, I've seen shiploads (pun intended) of that color paint! Wink

    Hi Peter

    Sorry about my silence there - I didn't see the posting until now... :-( The specific paint I used was "Dupli-Color Engine Enamel", "New Ford Grey", code: CDE1611. I bought the paint from an automotive supply company (Canadian Tire, actually) here where I live.

    Hi Charlie... Couldn't help smiling. Having a side interest in Naval vessels of the WW2 period, I'd say it is slightly darker than the Haze Grey as used in U.S. Navy Measure 22 (Vertical Surfaces) or the post-war period ;-)

    Yes, I'm sure you are correct on that paint shade. I do seem to recall that some equipment (electronics, etc.) pieces may have been darker grey. Of course that was all under artificial lighting so who can be sure. BTW, speaking of paint, I hope you didn't use red lead primer under that grey paint! Laughing

    I realize that this is an old thread, but how did you create your pictures?? I am asking because after I saved two of the under-the-chassis images, when I try to print them with Windows XP's Picture and Fax Viewer all I get is a black line, no matter what type of printer (ink-jet or laser-jet) that I try to use. When I look at the properties of the pictures I see that they were created with a Canon Camera but all the other properties look normal.

    So, the $64000 Dollar question is ..... how does one print them?? ( I have printed lots of pictures that I found on-line but have never run into the Black-Line Picture problem!! )

    Any info would be greatly appreciated.

    Jan -- please ignore my previous POST, as I downloaded the Picassa Photo Editor by google and used it to print your Mark III pictures. Thanks anyway!

    Hi Marty

    (Sorry saw this post only now)

    I know it is sort of Sacrilege to have a hybrid system like this, I've never had the opportunity to take a 3130 apart, but the old NAD 114 etc series like I use were really well-made - Alps pot (Blue Velvet), all 1% resistors etc etc. The real reason why I have so far failed to replace it though is that I love the sound of the built-in MC phono amplifier. One day I will get around to replacing it, tho....

    FWIW, I have always liked Mission speakers, ran a set of M71s for years but recentlly changed to Mission MX3s - wife "allowed" me some toys, I got a Cambridge 651C CD player + a DacMagic Plus at the same time.
